How can you tell if you're making love to a teacher,a nurse or an airline stewardess?

A teacher says we got to do this over and over again til we get it right.

A nurse says hold still this won't hurt a bit.

And a airline stewardness says put this over your mouth and nose and breathe normally.

A guy and his manager
go down to the docks. The manager is betting every docker he sees that his guy
can make love to 100 women in a row, without pausing, and satisfy them all.
Bets are made, and they agree that they'll meet the next day. The next day, 100
women are lined up along the dock . The guy drops his pants and starts.
True to his word, he moves from one to the next, satisfying each one without pausing:
1.. 2.. 3.. on and on he goes: 49.. 50.. 51.. He slows down somewhat: 83.... 84....
85.... but he is still moving from one to the next, and the women are still satisfied:
97............ 98............. 99.............
...and before he can get to the last woman, he has a heart attack and dies.
The manager scratches his head in puzzlement and says, "I don't understand it!
It went perfectly well at practice this morning!"
